Why Mobile Websites Look Broken on Desktop Screens
When developers build Progressive Web Apps (PWAs) or mobile-first web applications, CSS layout engines scale elements to fit the viewport width (`100vw`). On a desktop monitor (1920x1080 or larger), this causes single-column feeds, full-bleed images, and mobile navigation bars to expand horizontally, creating a distorted, unnaturally wide layout.
The Three Common Ways to Fix Mobile Layouts on Desktop
- Use Max-Width CSS Containers: Constrain your main wrapper to `max-w-md` (`448px`) or `max-w-lg` (`512px`) with `mx-auto` centering.
- Chrome DevTools Emulation: Open Developer Tools (`F12`), press `Cmd + Shift + M`, and select a mobile device viewport. (Ideal for local testing, but unsuited for sharing with clients or investors).
- ViewCore Device Mockups: Paste your URL into ViewCore to create a shareable presentation link (`viewcore.xyz/yourname/demo`) that locks your app inside an interactive iPhone or iPad frame.
Frequently Asked Questions
Does ViewCore alter my website's code?
No. ViewCore renders your live web application inside a sandboxed viewport wrapper with simulated hardware cutouts and status bars.
Can clients interact with my app inside the phone frame?
Yes! ViewCore provides interactive touch-event simulations so users can click, scroll, tap buttons, and fill out forms naturally.
